Easytrieve: SEARCH logic

For each record in the IN1 file, the below program carries out binary search in IN2 file. So, the IN2 file should not have any duplicates for the key field. The key field in the IN2 file should be defined as "ARG" and the second field should be defined as "DESC". The table file (IN2 file) can have other data along with ARG and DESC fields, but only ARG and DESC should be defined in the file section.  The "IF IN2" condition verifies if the search is successful.
